<b>Abstract:</b><br>

The Java Data Objects (JDO) API officially became

a Java standard via the Java Community Process

during the week of JavaOne 2002.

JDO provides transparent persistence of Java object models

in transactional datastores. The state of Java objects

are mapped automatically between the database and memory.

JDO has a query language derived from Java that allows

applications to express queries based on the application's object model.

Applications navigate their object model using standard

Java constructs like references and collections.

The JDO implementation transparently manages a cache

of all objects accessed by the application.

JDO implementations are already available for

object and relational databases.

This seminar provides an overview of this new

and strategically important API.

It includes a walkthrough of a small example

illustrating how objects are persisted, queried,

read, modified and deleted.

</p>

  <p>

  <b>About Speaker:</b><br>

David Jordan has been an active member of

the JDO expert group since its inception.

He has actively worked with transparent

object persistence technologies since 1985,

storing object models in flat files, network,

relational and object databases.

He will be co-authoring a book on JDO

with Craig Russell (the JDO specification lead at Sun)

to be published by O'Reilly & Associates.



He is the author of the book "C++ Object Databases"

and is co-editor of four books published

by the Object Data Management Group (ODMG).

He has used many of the commercial implementations

of object persistence and has served as an advisor

for three object database companies.

David founded Object Identity, Inc. to provide JDO

consulting and training services.

He recently has been selected to serve as the moderator

for the JDOcentral.com community web site,

which provides numerous JDO-related resources.</p>
